Hi Folks, I have been trawling thru the forum looking for a straight answer to this but so far I am none the wiser. So please excuse me opening up a new thread!

My question simply:-

Which triple pedal does Korg recommend for the Kronos?

The manual I have suggests a PU 1 which appears to be a cheap switch. The only triple pedal on the Korg site is the PU2 which seems to have an unusual connector cable for Korg pianos. I would be happy to do a mod if I knew how the wiring was set up.

Or should I go for a third party pedal like the Studiologic VFP-3-10 which has a regular mono jack and a TRS jack (possibly working with the Kronos 2 sockets.)

I'm gonna say that I think it doesn't really matter the model imo I haven't tested but usually this kind of thing is not made for only one specific model, since I can use my korg pedal on other instruments as well and also other synths. So that said I think it would be only a matter of changing polarity on global panel to be able to have the right signal you want. But again I'm speanking with the base on the sustain pedal only cause I don't own a triple pedal and never tested it.

Sure I understand all that. In the absence of a dedicated Korg Triple pedal I'm quite happy to use something else, but I really need to know how to wire it up.
i.e. Two sockets on the Kronos. 3 pedals. ???? Sustain - Sostenuto and Soft - (I'm really interested in the sostenuto for Impressionist stuff like Debussy etc.) For instance would it require a resistor in the circuit?

Well I did some research and actually there's not much about it. But I did find a guy tried a roland RPU-3 and it wasn't successfull so for this matter it drops what I was saying before that it should work on any synth and vice versa.
I think maybe the best option would be for you to buy 3 sustain pedals and make it some kind of pedal board for them or you could get the sustain from korg and the damper for korg. This way each one of them would be separately and work as intended I think. If you happen to have one you could give it a try on each jack and see if it does the work as intended.

Interesting that the chap in the link attempts to use the 'pedal' socket which I use for an 'Expression' continuous controller. This leaves only two sockets for the 'momentary' switches.

Unless anybody else on this forum has any other ideas it's gonna be a trial & error scenario.

Incidentally I use Yamaha FC7s & 9's as 'continuous' and FC4s as sustains. The NORD triple pedal doesn't work with Kronos (well the damper does) but that has a circuit board to do it's job with my NORD board.

The FC4 works with both 'Damper' & 'Switch' options but I think there is some other way of producing the 'Sostenuto' effect. Maybe I should be looking at doing this via MIDI.

At the end of the day it's no big deal - I can work with what I have. I do find it curious that even KORG don't seem to support their own product though!

For sure and it is also interesting that as you mentioned Korg says on the manual that you can use the PU-1 pedal. I've searched on google and it seems that this pedal wasn't even made because there's absolutely no pics what so ever nor any page even from korg mentioning anything about this pedal.

The only thing I found is a PS1 which is a little square footswitch! They're useless 'cause they won't stay where they're put, so you have to waste time looking to see where they've travelled to!! Lol !

Not if you make a little pedalboard with some velcro, I used to have that problem too but then when I've decided to make a pedalboard my problems were solved!
